Answer:
I. The hollow sphere has the greater angular momentum.
Explanation:
Given that the mass and radius of hollow sphere and solid sphere are same. Let the mass and radius of two spheres be m and r respectively. The two spheres are rotating having same angular velocity ω .
Moment of inertia of solid sphere, I₁ =
Moment of inertia of hollow sphere, I₂ =
Since, I₁ and I₂ are not equal. Therefore, the statement iv is wrong.
The relation between angular momentum, moment of inertia and angular velocity is :
L = Iω
Let L₁ and L₂ be the angular momentum of solid sphere and hollow sphere respectively.
L₁ = I₁ω and L₂ = I₂ω
As ω is same for both spheres but I₂ is greater than I₁, hence L₂ is greater than L₁.
Therefore, statement I is correct that the hollow sphere has the greater angular momentum.

On his first visit he saw a total of 25 birds: <span>12 Turkish vultures, 2 bald eagles, 4 northern goshawks, and 7 red-tailed hawks. And they expect 175 birds next year. If we divide 175/25=7, we find that there will be 7 times as many birds, so we now we can just multiply each amount of birds from before to predict next year: 84</span><span> Turkish vultures, 49 bald eagles, 28 northern goshawks, and 49 red-tailed hawks.</span>
